APPARATUS FOR LOCATING SHANK STIFFENERS ON SHANK PIECES FOR TURN SHOES.

Original application filed April 26, 1920, Serial No. 376,633.

fo all 1071.017?.y t may' concern:

Be it known that I, REINHARD E. BAR'rELs.l a citizen of the UnitedStates, residing at Lynn, in the county of Essex and State ofMassachusetts, have invented new and useful Improvements in Apparatusfor Locating Shank Stiffeners on Shank Pieces for Turn Slices, of whichthe following is a specification.

In assembling rigid shank stiffeners 1n shoes, the forward end of theshank stiffener should be located a short distance back of or below thebreak line of the sole in order that the resiliency of the shoe at thebreak line may not be impaired and the shoe thereby ruined.

`The shank stiffener is attached to the shank of the sole or in turnshoes to a shank piece having a heel and shank but no forepart, whilethe sole or shank piece is fiat and before it has been shaped to itsfinal form, and for this reason it is difficult to judge when locatingthe stiffener, where the break line will be on the sole or shank piecewhen the shoe is completed. Consequently, many soles have been spoiledby the location of the shank stiflener too far forward or too far backrelative to the break line, in the first instance. destroying theresiliency of the sole at the break line, and in the second, throwingoff the tread of the heel, either of which faults is undesirable fromtlre standpoint of good workmanship, if not,` fatal to the usefulness ofthe shoe.

'The break line on the turn yshoe shank has no definite location and isarbitrarily determined by the manufacturer. That is, in placing theshank in the shoe, the manufacturer may extend the forward end of theshank as far forward of the break line of the shoe as his fancy orjudgment may dictate. In view of the arbitrary location of the breakline as set forth above, the position of the forward end of the shankstiffener on the shank may be determined by measuring rearwardly fromthe forward end of the shank a distance equal to the distance of thebreak line therefrom plus the distance that the forward end of thestiifener is to be positioned back of the break line.

One object of my invention is to produce a gagingapparatus whereby theworkman can quickly and accurately locate the stiffener on the shankpiece for any given style and size of shoe.

Divided and this application filed May 17,

Serial N0. 561,593.

Another object of my invention is to provide means whereby when thedesired point for the end of the shank stiifener on a shank piece of onesize of a certain style has been located, the corresponding pointfor anyother size of that same style may be readily located.

A still further object is to produce mechanical means whereby thedesired point 1n any given shank piece may be readily and accuratelylocated. y

A speciiic embodiment of my invention by which the above objects may beaccomplished is illustrated on the accompanying drawings, thisapplication being a division of application Serial Number 376,633 filed.

April 2G, 1920, for apparatus for locatingv4 shank stiHeuers in shoesoles.

Referring to these drawings,

Figure l is a plan of the apparatus showing a shank stifener in placethereon and the shank in dotted lines.

Figure 2 is a. longitudinal section on line y 2 2 of Figurel.

Figure 3 is a section on line ure 2.

Figure 4: is a plan of the shank with the stiliener attached thereto.

Figure 5 is a side elevation showing the shank and stiffener molded toform for use in a shoe.

Figure 6 is' a side elevation of a shank stifl'ener.

In the case of a turn shoe, while the shank piece is in the form of aHat blank, the stiffener is preferably formed prior to attachmentthereof to the shank, with a longitudinal ridge extending to within ashort distance of the ends thereof. A form of 3-8 of Figstilfener to beused with a turn shoe shank is illustrated at 4t2 in Figure 6, thelongitudinal ridge being indicated by the reference numeral 43 and thesecuring tines by the numeral 44. It will be noted that these tinesextend from the opposite side of the shank stifliener from that on whichthe ridge is located.

Referring to Figures l, 2, and 3, 50 ,indicates a plate provided withmeans for holding the shank stiiiiener in fixed position thereon. Thismeans comprises a support for the shank stiffener preferably formed bycutting a slot 51 longitudinally through the plate and covering saidslot with a thin sheet of metal 52,- as brass, aluminum, or the like,

llO

' upwardly therefrom 'formed with a longitudinal depression therein. Thepurpose of this depression is to receive the ridge of the shank stitenerwhen said stiii'ener is placed on the plate, as will hereinafter be setforth. Border-ing the slot 5l on three sides is a U-shaped brace member5st, which serves to hold the sheet ot metal in place and preventslateral displacement of the shank stitfener, when placed on the plate.This brace member may be formed integral with the plate but ispreferably made separately and attached thereto in some suitable manneras by a screw or the like, (see Figure l ot the drawings).

Located a short distance in .front of the brace member 53 is an abutmentmember against which the forward end of the shank stitliener abuts whenplaced between the arms ot the U-shaped brace member in position to beattached to the shank. rlhe U-shaped member 54: may be madelongitudinally adjustable to adapt it to confine the shank stitlener inits position abutting` against the member 55 if so desired. For thispurpose the plate 50 is shown in Figure 2 as provided with a pluralityof threaded openings in any of which a screw 50() for fixing `the member5a thereto may be passed.

The plate is also provided with suitable guide members for positioningthe shank in proper relation above the shank stitfener to be attachedthereto. There may be any suitable number of these guide members, threebeing shown in Figure l, comprising an end guide member 56 in front ot'abutment 55, and two side guides 57 and 5S. rl`he guide members areL-shaped, having long arms which lie against the plate, and shortabutment arms 56", 57, and 58a which project forming abutments againstwhich the shank is placed in positioning it above the shank stiffener.The guides are provided with suitable means whereby they may be adjustedto a shank otl any dimensions and to position the same with itslongitudinal median line directly above that ot the stifl'ener. As shownin Figure l, this means comprises slots 45 in the long arms of theguides and set screws 46 located in said slot and screwed into theplate.

lilith shanks to be treated alike, the operation is as follows: Thedistance on -the shank relative to the break line, as indicated above isdetermined and measured forwardly on the plate trom the rear ot theabutment member 55 and abutment arms 56 placed at this point, and theside guide members 5T and 58 are set so as to position the shank abovethe shank stiftener in order that the longitudinal center lines of bothof these members will coincide. lVhen the device is so set, a shankstitfener is slipped into place with the tines extending upward and ashank is placed thereabove abutting the brace members in the manner, asset t'orth above, and is struck with a hammer at a point above where thetimes are located.

In practice, it is desirable in this operation to attach the shanksupport to a turn shoe shank only at the forward end and securely enoughfor the two members to remain attached in proper position relative toeach other until the shank, which at this stage is in the form of a fiatblank, can be molded into a suitable shape to be placed in a shoe. Theshank stiifcner is fastened securely in place in the molding of theshank to Jform. Under some circumstances, however, it is desirable toattach the shank stit- 'ener to the shank at both ends in the initialoperation and by a single operation ol' the machine.

In order to facilitatethe setting ot the end guide member to suitvarious sizes and styles of shoe, plate 5() may be provided withlongitudinal graduations corresponding to the various lengths of shankpiece for any given size, a cooperating reference line being made on theguide member 5G for each style requiring a different setting` of theguide member. By bringzjnfa,` the style mark in registry with the sizemark tor the size desired, the guide 56 is correctly positioned forlocating the stiffener on the shank for that size and style. Graduationsfor the side guides 57 and 58 are not important since it is an easymatter to set them so as to position the stifener in the longitudinalcenter ot the shank.

Having thus described an embodiment ot this invention it should beevident that many changes and modifications might be made thereinwithout departing from its spirit and scope.

I claim:

l. A device for locatinga shank stiffener in a desired position on ashank, comprising` a support, means on the support for holding` theshank stitl'ener deiinitely positioned on the support, and abutments onthe support against which the shank may be placed so as to position theshank above the shank stitl'ener in position to be attached thereto inthe desired position.
